There were 10 probable resistance genes characterized in these cultivars, in which, <em>Yr9</em> was most commonly postulated to be present in thirteen cultivars. <em>Yr21</em>, the second, was present in four cultivars. <em>Yr8</em>, the third, were present in three cultivars. <em>Yr6</em>, <em>Yr17</em> and <em>Yr26</em>, the fourth, was present in two cultivars respectively.

One cultivar (Yunmai 42) had no resistance gene tested in this study. Cultivars such as Yunmai 52, Mian 1971-98, Kunmai 4, and Yunmai 56 carried effective genes and can be popularized mainly; <em>Yr9</em> should be planted with other <em>Yr</em> genes. In the meantime other effective genes should be introduced to realize gene diversity for controlling wheat yellow rust. Yunmai 42 should be reduced to avoid rust breakout. Unknown gene cultivars should be utilized and be researched deeply.</p></div>","PeriodicalId":7475,"journal":{"name":"Agricultural Sciences in China","volume":"10 11","pages":"Pages 1723-1731"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1671-2927(11)60171-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"56762223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment was conducted in a split plot design with three replications with water supply regime as the main plot treatment and first cutting date as the subplot treatment. Two water supply regimes were used, which included rain-fed treatment as control (CK) and a single irrigation and straw mulch treatment (W).

The study involved five treatments: organic manure (NPKM), fertilizer NPK (NPK), fertilizer NP (NP), fertilizer NK (NK), and control (CK). Manured soils had higher crop biomass, organic C, and pH than soils receiving the various mineralized fertilizers indicating that long-term application of manures could efficiently prevent red soil acidification and increase crop productivity. The application of manures and fertilizers at a rate of 300 kg N ha⁻¹ yr⁻¹ obviously increased N₂O and CO₂ emissions from 0.58 kg N₂O-N ha⁻¹ yr⁻¹ and 10 565 kg C ha⁻¹ yr⁻¹ in the CK treatment soil to 3.01 kg N₂O-N ha⁻¹ yr⁻¹ and 28 663 kg C ha⁻¹ yr⁻¹ in the NPKM treatment. There were also obvious different effects on N₂O and CO₂ emissions between applying fertilizer and manure. More N₂O and CO₂ released during the 184-d maize growing season than the 125-d wheat growth season in the manure fertilized soils but not in mineral fertilizer treatments. N₂O emission was significantly affected by soil moisture only during the wheat growing season, and CO₂ emission was affected by soil temperature only in CK and NP treatment during the wheat and maize growing season.

Dumpling quality is determined by the characteristics of both flour and filling, thus improvement of flour quality plays an important role in improving dumpling quality. Thirty-nine Shandong winter wheat cultivars and advanced lines sown in Jinan, Shandong Province, China, in the 2008–2009 cropping season were used to determine genetic variation in Chinese raw dumpling quality and its relationship with flour characteristics. Large variations were observed for protein quality parameters in comparison with starch properties. Variation in color of the raw dumpling sheet was broader than that of sensory evaluation parameters of boiled dumpling among tested wheat cultivars, indicating the large influence of filling on dumpling color. Two cultivars, Jimai 20 and Zimai 12, were identified as possessing very good quality of raw dumpling, and 21 cultivars and advanced lines showed good quality. Protein and total starch content influenced the <em>L^*</em> value of raw dumpling sheets. <em>L^*</em> value at 0 and 2 h after sheeting were significantly influenced by protein content (<em>r</em>=−0.46 and −0.52, <em>P</em>&lt;0.01) and total starch content (<em>r</em>=0.55 and 0.57, <em>P</em>&lt;0.01), respectively.
